Redundant Open User Communication
https://support.industry.siemens.com/cs/document/109763719/redundant-open-user-communication
Monitoring and automatic connection switchover for up to four lower-level connections based on the TCON blocks of Open User Communication.
The TCON block is used for programmed connections when establishing a connection via Open User Communication (OUC). However, this does not provide the option of an alternative connection path in the event of a connection fault.
The TCON_RED blocks expand the functionality of the TCON blocks with monitoring and automatic connection switchover for up to four lower-level connections.
TCON_RED blocks search for an active connection from the available connection parameters. A test connection is additionally established between both communication partners for fast connection diagnostics and monitored by means of test telegrams. If the monitoring determines a connection fault, the test connection and active connection are disconnected and a search initiated for a new active connection.
Documentation and block library TIA 15.1
